How the Chile permiso de circulación calculator is verified
Inputs
| Input | Field | Type |
|---|---|---|
| Tasación fiscal SII (CLP) | tasacion | number |
The formula
Each derived value below is computed by the Valem engine from the expression shown, in this order. Nothing else runs — there is no hidden code path.
| Derived value | Field | Formula (JSONata) |
|---|---|---|
| Tasa | rate | ($v := tasacion; $v <= 15000000 ? 0.015 : $v <= 30000000 ? 0.03 : 0.045) |
| Permiso anual | permiso | $round(tasacion * rate, 2) |
Test vectors (2)
Every case is executed against this model on each build, by the Java engine and independently by a JavaScript one. A mismatch of a single cent fails the build, so the page cannot ship advertising a figure the model no longer produces.
Case 1 — C1 tasación 12M CLP
given tasacion | 12000000 |
|---|---|
expect rate | 0.015 |
expect permiso | 180000 |
Case 2 — C2 tasación 30M CLP
given tasacion | 30000000 |
|---|---|
expect rate | 0.03 |
expect permiso | 900000 |
